Specication of Letters Patent.

Application led November 2, 1914. Serial N o. 869,941.

To all whom t may concern:

Be it known that I, LUDWIG T. KUnHL, a citizen of the United States, residing at Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Filing- Cabinets, of which the following is a specification.

My invention relates more particularly to card cabinets, though as will be apparent, it is in some of its features applicable to other forms of cabinet as well. The purpose of the invention is to provide a cabinet of this character in which the drawer may be readily drawn out to its full eXtent without danger of dropping from the cabinet or holder and yet may be readily entirely removed when desired, there being a stop so arranged in connection with the drawer and case that the insertion of the drawer puts itinto operative position and yet it may be readily withdrawn from operative position by the fingers when the drawer is to be entirely withdrawn. v s.

A further object of theV invention 'is to provide means whereby the slides upon which thedrawer is mounted are fully withdrawn from the casingwith the drawer before the drawer moves with relation thereto, in order to avoid binding. Other features of the invention will appear in connection with the following specification and claims.

In the drawings I have shown and in the specification described in detail a preferred form of my invention as applied to a metallic cabinet but it is to be understood that my invention is not to be limited by theV specific disclosure but is set out in the following claims in which I have endeavored to distinguish it from the prior art so far as known to me without, however, relinquishing or abandoning any feature thereof.

In the accompanying drawings Figure 1 is a vertical longitudinal section of a drawer and case embodying my invention on the line 1-1 of Fig. 3; Fig. 2 is a vertical longitudif vnal section of the same upon the line 2-2 of Fig. 3; the drawer, however, being shown extended and the case broken away; Fig. 3 is a horizontal plan through the line 3-3 of Fig. l; Fig. 4 is a transverse section partly broken away upon the line 4-4 ofFig. l; Fig. 5 vis a detail in side elevation ofone of the slides upon which the drawer is mounted showing also the guide in which the slide works, and Fig. 6 a fragmentary horizontal section on the line v6 6 of Fig. 4.

Each part is designated by the same reference character wherever it appears in the several views.

The casing 7 may be of any suitable form or material but is here shown as generally rectangular and struck up out of sheet metal, the corners being rounded as shown. An entrance for the drawer is formed in the front end by cutting an opening of suitable shape therein and bending back the edges of the metal as at 8 to form an inwardly eX- tending flange. YThe guides 9. for the slides 10 upon' which the drawer is mounted' are supported from the side walls by brackets 11 brazed or otherwise secured to said walls, and at their rear ends to the rear wall 12 of the case by angular brackets 13 which are brazed or otherwise secured to the casing and the guides. These guides eXtend parallel to the top and bottom of the case and are preferably formed of sheet metal having their opposite longitudinal edges 14, 15 turned overand toward each other. The slides 16 are also formed of sheet metal and have their opposite edges turned over as at 17 so that the slides are strengthened by said flanges and made to fit snugly within the grooves formed by the overturned edges of the guides. One edge of each `guide, as shown the upper edge, is vcut away as at 18 to'form a shoulder at 19 and thecorresponding turned over edge or flange 17 of the slide is cut out as at 20 to form an inwardly eX- tending tongue 21 which when the slide is fully drawn out engages the shoulder '19. Inthis manner is formed a pairof opposing stops which permit the slide to be drawn outward as far as is desirable and then prevents its further'movement. Preferably the movement so permitted is about one-half the length of the slide.l

The drawer is likewise preferably formed of sheet metal and its sides corrugated at 22, 23 for the purpose of lending additional rigidity to the structure and in the case of the latter corrugation -to provide outwardly extending vprojections to which the drawer slides 24 may be riveted or otherwise attached. It will be understood that these drawer slides are also 'of sheet metal but with unturned edges which are received within the grooves formed by the overlappingedges lief.theintermediateslides. In orderl thatgthe intermediate slides'. 16 may. be drawn outhto' the fullest extent or in other words until arrested by the stops before the drawer moves relative thereto, springsg25 are attached by rivets or otherwise along. the `initier:walls.andwlthin the grooves 23 of Y the drawer butv opposite the openings 26, formed in the draweriwallsand drawer slides respectiyely yare outwardly bulged or curved, as at '28 'tof project into thevv openings in the-drawerwalljand alzsoi'nto the openings 27 inthe intermediate slide when vthe two openings are in registry. The forward end 29 of the'springrestsagainst the wall of the 1drawer and limitsV the outward lmovementofthe' spring.y It will now beseen'th'at as the drawer is drawn outward the spring, a'tirs't', while the guide presents' no great resistance, draws. the' lattery outward with the drawer 'but when th'eslidereaches .the end ofitsrnovement then the-further movementof the drawer overcomes thel resilience ofthesprin'g andjpermitlsvthe drawer to be further'drawnfout ywhile the slide remains stationary.nv Thus when the drawer is drawn y litward'jboth of the intermediate slides accompany it untilarrested bythe stops .referred to above, w hen the further-:movement of the drawer isin relation to the slides.

Inv order that the drawer may not be carelesslyl withdrawncompletely fromA the casing, I 'provide vitat its rear end withT a stop 3.0 which engages"the` lower edge 31 of the front opening whenthex drawer is fullyextended. 'In ordenhoweven-that'the stop 'shallnot absolutely' preventthe withdrawal of the-drawer ,wheniitis desired toremove it fromithcabinetythe stopis mounted to slide verticallyin` aguide' 31,' but frictionally hel'd in adjustable.position.rv At the krear Vend of thecaseand .in position to kengage the upper end of themovable'stop'c30', I attach a cam 32fasshowni-11Fig. 1. Wheh'the draweris thrust inward, if. the stop 30 happens toV be in anyf-bu't its vlowe'rmost position, it engages the` cam Iand in itsY further movement is driven downward into, the position in which it engagesthe lower edge 0r lip of thefron't opening whenthe drawer is againdrawn outward. If, however, it is desired to remove' the drawer completely from thel cabinet it may be drawn outward land the fingers inserted to reach the slide 30and draw it I'upwardiso thatits lower-fendY 33 no longer engages the' edge v1of L the front'opening. vThe drawer; Ainserted in the case with the slide-in this non-'engaging position but when the 'drawer is fully closed'orsubstantially so the cam 32 again rreturnsthestopto lits operatve' posit'on'as' beforeexp'lained.

In order to ravoid unnecessary .noirse and and prevent niarring furnitureY orn which' it may "beplfaced, the drawer 'is provided with felt strips 34, 35 which are attached beneath the same at its front and rear edges'respectively..l l ,Y

In case the drawer` is vto, be n usedpfor containing cards yand locking them'the'rin, the front panel of the drawer is formed with a perforation 36 through which a locking rod 87 is inserted, the rod being provided with a knob 38'y screwed thereto and havingy a neck 39 which is grooved at 40 for a purpose which will presently appear. The inner face 0f the front wall isprovided with a slightly bulging. liner 41 between which and the'frontY wall is arranged va vsheet metal guide 42- fr a lockingk tongue 43.V Saidtongue slides .vertically in the guide-and; at itslwer e'nd is notched to embrace the neck ofthe rod and enter the;y groove' 39 therein; The rod is thus normally held inV position but if desired it-may be'removedby opening the drawer slightly and lifting lthe locking said' intermediatefslides, there beingppenings Yin the4 sides ofthe drawer. and slides-respectively adapted Y to register when the drawerk is in itsi innermost;positions-,and leaf springs mounted within the drawer havlng curvedk odset-portions' adapted to enter sai'dopening's and yieldingly enga-ge the intermediate slides.
